Device to draw threads between a beam and a winding machine

Device to draw threads (11) and/or broken threads (111) being unwound between a beam and a winding machine (13), the device cooperating with one guide tube (14) per each thread (11-111) and comprising a plurality of guide tubes (14) in close proximity to each other, each guide tube (14) including a conveyor tube (32) comprising means to aspirate/eject thread, which can be momentarily actuated and are associated with means that sense broken thread (111) and with means for the controlled braking and acceleration of the beam of the winding machine (13), the means to aspirate/eject thread being associated with an airtight box-shaped chamber (17) containing a plurality of guide tubes (14) and put momentarily under pressure, the thread aspiration/ejection means consisting of injection holes (21) which connect at an angle the box-shaped chamber (17) to the inside of each conveyor tube (32).
